Sunshine Silver Expands Land Holdings in Idaho by 60% and Announces New Drilling Programme
Sunshine Silver Mining & Refining Company (NYSE:SSMR) has increased its mineral rights holdings in Idaho's Silver Valley by approximately 14,100 acres—marking a 60% expansion. This brings the company’s total land position to around 38,000 acres and supports a new multi-year surface exploration programme targeting potential discoveries beyond the existing Sunshine Mine. The firm plans to conduct 45,000 metres of drilling across three priority areas: East Sunshine, Rock Creek, and Pine Creek. These targets were identified following fieldwork in 2025 that included extensive sampling efforts. The expanded land position is expected to offer significant exploration potential due to limited modern activity on much of the area. In parallel with surface operations, underground drilling at the existing mine continues as part of a separate programme aimed at supporting an upcoming feasibility study and assessing resource expansion opportunities.
